I use this as a reminder.

Configuring Cisco Repeater Access Points

Cisco access points that have two radios, such as my 1131AG Aironet, can act as a repeater access point. One of the radios is configured as a repeater role-station, while the other remains the root role-station.

Remember: Daisy chaining access points like this will hurt throughput. Because each repeater must receive and then re-transmit each packet on the same channel, throughput is cut in half for each repeater you add to the chain.

Also: You cannot configure multiple VLANs on repeater access points. Only the native VLAN is supported.
